NASA’s Hubble Offers Cosmic Sampler of Targets for Roman
If Roman finds a particularly interesting lens, researchers may use Hubble to take follow-up observations using its visible and UV prowess for individual objects.
Key points
- Huang (University of San Francisco); Processing: Gladys Kober (NASA/Catholic University of America) A gallery of gravitational lenses captured by NASA’s Hubble Space Telescope showcases the diversity of this cosmic phenomenon and lays the groundwork for follow-up observations by the new Nancy Grace Roman Space Telescope.

- While Hubble gets a better view of individual lenses, Roman will be able to capture more lenses with its wider field-of-view.
By studying Hubble lens images in detail, researchers intend to build a super-intelligence tool to efficiently search similar arcs in the upcoming Roman images.
The Hubble images are expected to both yield their own results on dark matter and pave the way for analysis of Roman’s larger sample of lenses.
Additional details
- With Hubble’s high-resolution imaging and precise models, researchers should also be able to detect small imperfections in these gravitationally lensed galaxy arcs that would indicate the presence of small clumps of dark matter.
- Hubble views the cosmos primarily in visible and ultraviolet light with some infrared coverage, providing a comprehensive, high-resolution view of individual objects.
- Roman sees primarily infrared light and some visible, over a much larger field of view to create panoramas of the universe.

- Gravitational lensing, first predicted by Albert Einstein, occurs when the gravity of a massive foreground object, such as a galaxy or cluster of galaxies, bends, warps, and magnifies the light from a more distant background object.
